Despite reports to the contrary, "there are no talks about reconciliation," a source close to the situation tells PEOPLE.

"Khloé is very frustrated when it comes to Lamar. The fact that he doesn't seem to care to shape up makes Khloé act like she is over him."

Another source confirms they are not in a good place. "Khloé doesn't know how they'll ever be a happy, married couple again," says the insider. "She is very hurt that he's lied to her about being clean. And she's made it clear that he can't spend time with her family until he is."

A rep for Kardashian did not respond to a request for comment.

On Sunday's episode of Keeping Up with the Kardashians, filmed in early August, viewers saw a visibly uncomfortable Khloé fielding repeated calls from Lamar while on a family camping trip.

"I laugh to keep from crying," she said on the show, which also revealed that Lamar left their home and was MIA. Speaking to Lamar through the cameras, she said, "You're not my child. I can't lock you in a room, as much as I would like to."

Three months later, it appears not much has changed for Khloé and Lamar, who has been struggling with drug issues while facing rumors of infidelity.
